BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to docking connectors for mobileelectronic devices. In particular, embodiments of the present inventionrelate to docking connectors disposed on a largest-surface-area surfaceof the electronic devices.

DISCUSSION OF RELATED ART

Mobile electronic devices often comprise docking connectors, whichenable the mobile electronic devices to temporarily attach to multipleexternal docking accessories, such as speakers and batteries, generallyfurther enabling power and data transmission between the mobileelectronic device and the docking accessories. Docking connectors aregenerally housed on one of the edges of the mobile electronic device, asopposed to one of the two major faces of a typical mobile electronicdevice, wherein the front face is generally designated by the locationof a screen, should the device house a screen, and the back face isdesignated as the face opposite the front face. For example, thesmartphone shown in FIG. 1A (Prior Art) has two major faces and fourrelatively narrow edges, with a docking connector housed on the bottomedge. A shortfall of housing a docking connector on the edge of a mobileelectronic device is that when the device is attached to dockingaccessories, the resultant system is generally inconvenient fortransport. If the docking accessories attach by a flexible cable to thedocking connector as shown in FIG. 1A, the resultant system comprisestwo or more independently moving bodies, connected by the flexiblecable, and is thus inconvenient for transport. If the dockingaccessories attach in a rigid fashion to the docking connector, theresultant system generally increases the effective magnitude of at leastone of the dimensions of the mobile electronic device to a degree thatrenders the resultant system inconvenient for transport. This is due tothe fact that the edges of mobile electronic devices generally have arelatively small surface area compared to the front and back faces ofthe devices; thus, to accommodate the volume of a docking accessory thatis rigidly attached to such an edge, the resultant system generallyextends significantly in directions away from the docking connectoredge. See for example FIG. 1B (Prior Art).

To address the preceding docking-system transport problem, some dockingaccessories, such as certain supplemental batteries, are manufactured asparts of mobile electronic device cases. The resultant “docking cases”attach to mobile electronic devices, both at their docking connectors(as standard docking accessories attach) and around their various edges(as standard mobile electronic device cases attach), to enable thedocking accessories to be transported securely against the back faces ofthe mobile electronic devices. See for example FIG. 1C (Prior Art). In asimilar vein, some docking accessories are manufactured as parts ofdocking “sleeves” (or “jackets”), which attach to compatible mobileelectronic devices at their side edges and at their docking connectors(some docking sleeves are themselves operable to form detachableattachments to independent docking accessories). See for example FIG. 1D(Prior Art). Docking cases and sleeves enable the majority of the volumeof docking accessories to be distributed in a generally even manneracross the relatively large back faces of mobile electronic devices,with the aim of minimizing effective increases in magnitude to anysingle dimension of the mobile electronic device and thus enabling theresultant systems to be transported in a convenient fashion. While goingsome way to mitigate the increase in effective size of mobile electronicdevices to which docking cases and sleeves are attached, the mainshortfall with this method for addressing the docking-system transportproblem is that docking cases and sleeves nevertheless can increase theeffective size of the corresponding mobile electronic device, both inthe dimension perpendicular to the back face of the mobile electronicdevice and in the dimension perpendicular to the face of the edge thathouses the docking connector.

A second method for addressing the docking-system transport problem isto (i) recess a portion of a selected edge of a mobile electronic deviceto form a rectangular cavity that is open both at the selected edge andat the backside of the mobile electronic device; (ii) form a dockingconnector on the recessed edge; and (iii) form rails (or tracks) on thetwo cavity edges perpendicular to the recessed edge. See for exampleFIG. 1E (Prior Art). The rails serve to guide docking accessories asthey are inserted into the rectangular cavity through the opening on theselected edge and to help fix the positions of the docking accessorieswhen they are in their docked states. The rectangular cavity enablesdocking accessories to attach to the mobile electronic device withoutincreasing its effective carrying size. For certain designs, the initialformation of the cavity may lead to an increase in the initial carryingsize of the mobile device by taking up space that could otherwise beused for internal components of the device; still, the cavity enablesdocking accessories to attach to the device without further increasingits effective carrying size and without altering its overall contour.This method thus avoids the main shortfall with the preceding method.Nevertheless, it has several shortfalls of its own. One shortfall withthis method is that its rail system requires the corresponding accessorycavity to be open at one edge of the mobile device. This isdisadvantageous, as edge openings reduce available space formobile-device features that are ideally located on an edge of the device(for instance, volume buttons, power buttons, built-in speakers, andbuilt-in sensors) and, if the selected edge is tapered, as is common tocreate the perception that the device is only as thick as its outermostedges, the tapered boundary of the corresponding accessory cavity placesadverse constraints on the design of compatible docking accessories.Another shortfall with this method is that, by fixing the positions ofthe outer edges of attached accessories through its rail system, itpresents design obstacles for a broad range of accessories whosefunctionality improves with the ability to expand away from, and rotateat various angles to, the backsides of the mobile electronic devices towhich they are attached (for instance, speakers, electrophysiologysensors, massage paddles, hand-pump chargers, and ultrasoundtransducers). Another shortfall with this method is that accessorieswhose attachment does not increase the effective carrying size of themobile device must have a certain rectangular shape and size to matewith the rail system (and those accessories that protrude beyond theboundaries of the rectangular cavity must have a base of a certainrectangular shape and size to mate with the rail system). Differentdocking accessories have different ideal shapes and sizes, however. Forinstance, whereas certain camera lenses, speakers, and electrophysiologysensors might ideally be circular and relatively small, certain gamecontrollers, external keyboards, and solar panels might ideally beelongated and relatively large.

What is needed is a docking platform that is housed on the back face ofa mobile electronic device to enable multiple docking accessories ofvarious shapes and sizes to simultaneously and independently attach tothe mobile electronic device with the optional freedom to expand awayfrom, and rotate at various angles to, the back face of the mobiledevice, and with at most a nominal increase to the effective magnitudeof any one dimension of the mobile device. Furthermore, the dockingplatform should not require openings on the edges of the mobile device.

SUMMARY OF THE INVENTION Cavity-Recessed Accessory Embodiments

Some embodiments of the present invention, as shown herein, are directedto mobile electronic devices having docking connectors. One of theseembodiments of the device includes a docking platform formed at one ofthe largest-surface-area surfaces, i.e., a selected surface, of themobile electronic device. In the present embodiment, the selectedsurface is the back surface of the device. In a separate embodiment, theselected surface may be the front, screen supporting surface. Thedocking platform is formed with a docking connection system whichincludes one or more docking connectors generally disposed in a recesseddocking accessory cavity. The docking connection system is configured toenable the recessed docking accessory cavity to be open only at theselected surface.

In some embodiments, the recessed docking accessory cavity enables oneor more docking accessories to be attached to the docking connectorswithout significantly increasing the effective carrying size of themobile electronic device. Docking accessories are manufactured to couplewith the recessed docking accessory cavity such that, when the dockingaccessory is in at least one mode of operation, the outer surface of thedocking accessory is generally co-planar with the selected surface ofthe mobile device.

In one embodiment, the docking connection system is formed toaccommodate a broad range of docking accessories. In the same orseparate embodiment, the docking connection system is operable to form adetachable attachment to multiple independent docking accessoriessimultaneously. In the same or separate embodiment, the dockingconnection system is operable to form a detachable attachment to onedocking accessory via two or more recessed docking accessory cavities.In the same or separate embodiment, the docking connection system may beoperable to form a detachable attachment radially inward from the outeredges of a circular accessory, to allow the body of the accessory totemporarily expand away from the docking platform by way of anexpandable conical accordion mechanism, whereby the foot, or narrowestpart of the accordion, which is located radially inward from the edgesof the accordion, forms the attachment point to the docking connectionsystem, and the mouth, or widest part of the accordion, forms anattachment to the body of the accessory. The range of dockingaccessories that may cooperate with the docking platform includes, byway of example, batteries, solar panels, game controls, LED lights,hand-crank chargers, weather sensors, camera flashes, camera lenses,electrophysiology sensors, memory cards, keyboards, massage paddles,glucose monitors, body fat monitors, breathalyzers, ultrasoundtransducers, and pulse oximeters. This list of possible dockingaccessories in not meant to be limiting in any way, but is merely meantto demonstrate the wide range of possible devices and technologies thatmay functionally cooperate with the present docking platform.

In one or more embodiments, the docking platform is integrally formedwith the body of the mobile electronic device. In a related embodiment,the docking platform is integrally formed with one aspect of the mobileelectronic device, e.g., the back cover. The docking platform may beformed with an accessory cavity that has a generally oval shape. In oneembodiment, the generally oval or capsule shaped accessory cavity(herein after, “oval shaped accessory cavity”) supports two circularcavities formed at opposing ends of the oval shaped accessory cavity.Optionally, a depressed region constituting the middle portion of theoval cavity may be formed between the two circular cavities. Each of thetwo circular cavities may include a docking connector, for example, anannular docking connector disposed at its center. A docking connectormay be formed with a connection mechanism, electrical contacts forcommunication one or both of data and power, and an optional alignmentmechanism. For example, in the annular docking connector embodiment,each docking connector may be formed with (i) an annular female snap-fitfeature, for attaching docking accessories securely to the dockingplatform; (ii) 30 electrical contacts disposed evenly around the inneredge of the female snap-fit feature, for transmission of power and datato and from docking accessories; and (iii) a male index key, to ensurethat the electrical contacts on a docked accessory mate with theappropriate contacts on the docking connectors. The electrical contactsare formed of gold-plated nickel-plated copper, with copper pads, andthe remainder of the platform is formed of the same hard material as therest of the body of the mobile electronic device. Other connectionmechanisms, electrical contacts for communication one or both of dataand power, and alignment mechanism may be used without departing fromthe scope herein.

DETAILED DESCRIPTION OF THE INVENTION

One advantage of the present invention is that it allows multipledocking accessories to attach simultaneously and independently to themobile electronic device. Some docking accessories, such as supplementalcamera lenses and flashes, stereo speakers, and electrophysiologysensors, naturally work together in pairs. As such the present inventionfulfills the need for a method that enables multiple docking accessoriesto attach simultaneously to the mobile electronic device. Furthermore,different circumstances might call for one and the same accessory to bepaired with different partner accessories. For instance, a daytimecircumstance might call for a supplemental camera lens accessory to becombined with a supplemental battery accessory, whereas a nighttimecircumstance might call for the same camera lens to be combined insteadwith a supplemental flash accessory. The present invention fulfills theneed for a method that enables multiple docking accessories to attachboth simultaneously and independently to the mobile electronic device.
